MECHANISM FOR OPERATING ADJUSTABLE WORK-PERFORMING MEMBERS.

Application filed December 18, 1902.

T 0 all whom it may concern:

Be it known that I, FRANOIs H. RIoHAnDs, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Mechanism for Operating Adjustable Work-Performing Members, of which the following is a specification.

This invention relates to an organization of devices adapted for cooperative association with one or more members each of which may be capable of and upon adjustment is designed for performing work of some description.

The present improvements are closely related to those constituting the subject matter of my ending application Serial No. 134,626, filec fDecember 10, 1902; the subject matter disclosed in this a plication is, however, distinguished thererom by reason of the fact that the present mechanism is adapted for selectively effecting the adjustment of the adjustable members through different distances.

In the drawings accompanying this specification an embodiment of my invention is illustrated, wherein Figure 1 is an elevation with the casing of the mechanism removed and some of the parts shown in vertical sec tion. Fig. 2 is a top view with part of the top plate removed. Fig, 3 is a plan view on a plane between the main and supplemental driving-shafts. Fig. 4 is a vertical section of a portion of the mechanism. Fig. 5 is a detai of lifting fingers and Fig. 6 is a detail of the ring 26 carrying the raceway 27 The mechanism is shown as mounted in and upon a casing 6 constituting the bed as it were of the machine, and in which casing are provided bosses 77 which constitute the bearings for the main driving or cam shaft 8, beneath which cam-shaft is shown a supplemental driving-shaft 9 mounted in bosses 10 of the casing. Shaft 8 is provided with a gear-wheel 11 fast thereon in mesh with a gear-wheel 12 fast upon the shaft 9. The driving-shafts are assumed to be continuously driven by means of a pulley 13 fast upon the driving-shaft 8 and driven from some suitable source of power, (not shown).

In the present organization the work-performing members, designated in a general way by A, are illustrated as type-dies 14 Specification of Letters Patent.

which are supported by a rotary carrier or head 15, the carrier being shown as provided with slide ways 16 in which are mounted slides 17 capable in the organization illustrated of movement in a plane transverse to the plane of rotation of the head. The head is shown as mounted upon a shaft 18, which is shown as u right and as transverse to the driving cams aft which in the drawings is shown as occupying a substantially horizontal position. It will be apparent, of course, that this arrangement may be changed in practice. In the present instance the head is organized to carry twenty typedies, there being five slide ways in each of which is mounted a slide provided with four dies. The number of slides and the number of dies upon each slide has, for the purpose of illustration herein, been arbitrarily selected. The die-slides are interchangeable, and if desired, the head may also be interchangeable, whereby a greater or less number of slides may be carried. The shaft 18 is shown as provided at its lower end with a reduced portion 19 stepped in a bearing 20 of a cross beam 21 rigid with the casing, and the upper end of the shaft is shown as held by an eye 22 carried by an arm 23 bolted to the top of the casing, which eye not only supports the rod but sustains the head from upward movement.

Each of the slides is provided with a lug or projection 24, and surrounding the head and secured to the frame by suitable screws 25 is shown a plate 26 provided with a channel 27 constituting a raceway wherein the lugs 24 may travel, which raceway serves to maintain the slides in their idle position. Adj acent to the working point or position, however, the raceway is provided with a transverse channel 27 whereby the slides may be shifted and their lugs raised out of channel 27.

In the present embodiment of my invention the parts are organized for continuous operation, each slide being brought serially into the region of the working position and certain selectors, manually operated or otherwise, may be employed for determining which die of the quota or group of dies upon the slide then at position will be brought to the exact working position. The entire set or series of members is moved angularly step by step. The entire number of dies are distributed upon slides, each slide having a quota of dies, which slides are capable of being moved transverse to the plane of such angular movement.

For imparting a step-by-step movement to the carrier a spiral gear may be employed comprising a worm wheel 28 fast upon the shaft 18 and a worm wheel 29 fast upon a shaft 30 journaled in bosses 31 in the frame of the machine and advanced step-by-step by means of a star wheel 32 fast on shaft 30, and in the present instance having as many arms 33 as there are slide ways upon the carrier, which star wheel in the present instance is moved by means of an arm 34 fast upon the shaft 8 and provided with a roller 35 for engaging the arms, whereby upon each rotation of the driving-wheel the head is ad vanced one step and the slide is moved from the vicinity of the general working position and another slide brought to such position. Each of the slides may be provided with a Working face, in the present instance constituting a lug 36 whereby some convenient device may be employed for taking hold of the slide and shifting it. There is shown located adjacent to the position occupied by such lug when the head has been brought to rest an arm 37 provided with a cavity organized to mate with such lug or projection, and upon shifting the arm after it has engaged the lug the slide may be shifted. The arm is shown as mounted upon a rock-shaft 38 mounted in a boss 39 upon the top plate of the inclosing casing and a bearing 40 in a bracket 41 of the frame. The rock shaft is shown as having an end projecting below the bearing and upon which end is mounted a head 42 provided with a slide 43 guided in ways 44 of the bracket 41 and provided with a depending leaf 440. To permit the shaft 38 to oscillate freely in the head 42 a channel or groove 380 is shown upon the portion within the head and a pin 382 running in the channel which holds the parts together and permits their ready disassemblage when desired.

There is shown mounted upon the supplemental driving-shaft a pair of cams 45, 46, which act uponda pair of arms 47, 48, res ectively, whici arms are fast upon a rock shaft 49, the arm 47 being organized to be acted upon by its cam and effective to rock the shaft in one direction and lock it in such position and the other arm and cam to rock the arm in the other direction and there lock it. An arm or lever 50 is mounted upon rock-shaft 49 and carries at its free end a series of fingers or push-pins 51, there being shown a number of fingers or pins equal to the number of dies upon each slide, so that upon any finger being pushed under the leaf 440 u on the rocking of the shaft 49 the arm 37 wi be raised a predetermined distance to bring a selected die to the working point or position. Each of the fingers is shown as in the form of a bell-crank-lever pivoted at 52 to the arm 50 and provided with some suitable means for returning it to idle position, in the present instance comprising a spring 53 bearing upon the arm 54 of the bell-cranklever and upon a fixed part of the arm 50. Suitable pins 55 may be employed for limiting the forward movement of the fingers and a back stop 56 may also be provided. Pivoted upon the same pivot 52 is shown an arm 57 having a hooked end 58 adapted on the elevation of arm 50 to project above the extreme upper portion of the leaf 440, whereby the shaft 38 may be returned to its normal position upon the lowering or return of arm 50 after it has been given an excursion by one of the fingers.

Manually operated selectors are shown, which in the present instance comprisefingerkeys 60 mounted upon key-levers 61 pivoted upon a suitable shaft 62 mounted in brackets 63 of the frame of the machine. Suitable means here shown as springs 64 may be employed for maintaining the keys at their normal or idle position. Upon the cross beam 21 at a position beneath the key-levers is shown an extension or shelf 65 wherein there are provided channels in each of which is located a push-pin 66. Suitable springs 67 may be employed for holding the push-pins at their inactive position, a removable plate 68 held on the shelf by means of screws 69 is shown for incasing the pins and springs. Each of the push-pins is located at the rear of one of the fingers 51 and in front of each push-pin is mounted a bell-crank-lever 70 loose upon a shaft 71 and having an end 72 adjacent to and adapted to engage with a push-pin and an end 73 beneath a finger or lug 74 upon the key-lever, whereby upon the depression of a key-lever one of the fingers will be pushed beneath the leaf 440 and upon the rocking of the shaft 49 the shaft 38 will be given an excursion and with it the arm 37.

For the purpose of bringing arm 37 in engagement with the slides the shaft 38 may be actuated by means of an arm or projection 78 secured to the shaft and lying in the path of an abutment 79 upon a link 80 which link is shown having a bifurcated end 81 resting upon the main cam or driving shaft and held in position between a collar 82 and the plane face of a cam-wheel 83, the cam face whereof is in engagement with a friction roll 84 upon such link whereby upon the link being given an excursion its abutmemt will engage the arm upon the sleeve and oscillate the same, causing the arm 37 to engage the slide, whereupon on such engagement if one of the jacks has been thrown under the leaf 144 the slide as well as the shaft 38 will be raised to bring the die corresponding with the depressed key into working position. After the arm has been raised and moved the slide, the cam face 85 upon the cam-wheel will come in contact with the roller 84 and advance the link 80 a further distance, which link is shown as pivoted at 86 to an arm 87 fast upon a rockshaft 88 mounted in suitable journals provided in bosses 89 on the frame and which also has fast thereon an arm 90 provided with a transverse elongated end or nose 91. Upon the advance of the arm 37 with the slide it comes opposite the end 91 of the arm 90 and upon the further advance of the link 80 it is pressed against the arm 37 and the slide which has been shifted is positioned and securely held by the pressure of the arm while at the point to receive the impact of Whatever work it is to perform.

In the present instance the work is not shown, but paper or other impression-receiving body may be passed thereto and in some cases may be in the form of ribbons or otherwise moved in front of the die, and between. such die and a suitable impressor, designated in a general way by 300, and shown as comprising a roll 92 mounted upon an arm 93 fast upon a rock-shaft 94 having suitable bearings 95 upon the top-plate of the casing, to which rock-shaft is fast an arm 96 and to which rock-shaft is pivoted a link 97 having a bifurcated end 98 embracing the main driving-shaft and held against the plane side face of a cam 99 by means of a collar 100, and which link is provided with a roller 101 riding upon the cam face of the wheel 99 whereby the link is advanced. A suitable spring 102 may be employed for returnirg the impressor and parts to their normal position. A suitable spring 103 may be employed for returning the link 80 to its normal position and oscillating the shaft 38 in the present instance shown as coiled around the shaft and secured thereto by means of a pin and secured to the bracket 40 by means of a pm.

For the purpose of holding the key-levers depressed until they have performed their entire work, each key-lever is shown as provided with a hook or engaging surface 105 adapted to engage a hook 106 pivoted therebelow u on a shaft 107 mounted in a bracket 108 of t e frame. The hook may be tripped after the operation is performed by means of a link 109 provided with a bifurcated end embracing the supplemental driving-shaft and having a roll 110 riding upon the face 111 of a cam 112 on such shaft, which link is pivoted to a lever 113 which is pivoted to the shaft 107 and has at its end 114 a pin 115 which will engage the hook 106 and draw it out of engagement with the hook 105, whereupon the lever held thereby will be permitted to assume its normal position responsive to the returning means employed therefor. Some means may be employed for returning the latch or hook 106 to its normal position and for causing it to lock with the hooks 105 after having been displaced by the contact of the two hooks. A spring 116 is here shown for such purpose, and a spring 117 is shown for raising the arm or lever 113, and moving the buffer 115 from contact with the latch. This spring also holds the roll 110 against the cam face 111.

The operation of the mechanical movement herein is as follows :The pulley is supposed to be driven continuously from some suitable source of power and to rotate in the direction of the arrow in Fig. 1, which will continuously rotate the main driving-shaft and the supplemental driving-shaft in gear therewith. The striker upon the main cam or driving shaft upon coming up will by its antifriction-roll engage one of the points or arms of the star wheel and shift the star wheel a step, which, through the spiral gear upon the star-wheel shaft and the shaft of the head, will advance or shift the head or carrier one step and permit it to rest with one of the die-slides adjacent to or in the general vicinity of the working point. All the other die-slides are held in idle position by means of their lugs traveling in the channel or raceway around the head and the dieslide which is halted in the vicinity of the Working point is contiguous to the transverse channel. After this angular shifting of all the dies the quota upon the slide referred to may be shifted individually, the amount of movement being selective, for which urpose the arm for engaging the slide wil be oscillated by means of the cam, link and sleeve provided for such purpose. The shifting, however, of the slide will be dependent upon whether or not one of the fingers upon the lifting arm has been pushed forward by means of a selector and its connected mechanism under the end of the shaft carrying the arm, whereby the amount of movement of the excursions imparted to the rock-arm will be determined. After the engaging arm has shifted the slide the organization of cams and levers is such that the supplemental pressing arm will be forced into engagement with the lifting arm and securely hold the slide in its shifted position, whereupon the further timing of the cams will actuate the impressor and the die will perform its work. The selectors, here illustrated as key-levers, will be locked in their depressed or active position to positively hold the selected finger in its advanced position until the time has arrived in the operation of the machine to permit the fingers to be withdrawn, when the machine will automatically release the key-lever and with it the parts holding the fingers at rest.
